Emsm, a citizen of the United States, residing at St. Louis, have invented a certain new and useful lmprovemenbinganose-Tip Switches, of which fine 1 is a clear, and exact descripfion suc as will enable others shlled in the are to and the switch points or switch rails that carry One object oi my invention is to provide a bard kip split switch which is so consir-noted that there is no liability of the switch rails break ng at the joints between the wheel tread smiacesoi the rails and the bard tips this are connected to tine rails.

Another object is "to provide a switch of the type mentioned, in which she lips are connected to the switch points or switch rails in such a manner that there is no liability of their working loose when the switch is in service. To ibis end i have devised a hard ri split switch in wbich the tip on each switch rail is provided with an integral reinforcing device arranged at the joint between the wheel tread surfaces of the hip and tbs switch rail, so as to reinforce and strengthen the switch rail at the point where it ismost liable to break, when the switch is in service, said reinforcing device preferably being in the form of a clip or bracket that serves to connect the usual switch rod to the switch rail. The web or" tbe switch rail preferably extends throughout the entire length of the no and the tip is provided with integral portions that embrace both sides of the web of the rail, so as to reduce the strain on the fastening devices used to secure the up to tbe rail, thereby efiectively prevenh'ng the tip fiom worlnng loose from .che switch rail.

Figure l is a top plan view of a split switch constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of said switch, taken on the line 22 of- Fig. 1. Figs. 3, d and 5 are cross-sectlonal v1cws, taken on the lines 33, 4=l and 5 5', respectively, of Fig. 2; and Fig. 6 1s a perspective view of one of the hard tlps that the switch points or switch rails are provided with. v a

. Referring to the (l1'&Wl11gS,'WhlGl1 illusirate the preferred form of my invention, ddesignates the switch points or switcb rails of a split switch, B designates the stock rods with which the switch points codperate, and C designates switch rods of any sultable type that join the switch points together and cause them to move in unison. Each of the switch rails A is provided with a tip 1) formed of manganese steel, or some ets or other suitable fastening devices 3 that pass horizontally through the web of the switch rail and through the verfical web 4 of the tip. in the preferred form of my invention as herein shown the web 2 of the switch rail extends throughout the entire length of the tip l) to the end of said sip,

as shown in broken lines in Fig. 2, and the web 4 of the tip extends rearwardiv beyond the joint betweenthe wheel tread surfaces of the tip and the switch rail so than it will lap over the web of the switch rail some distance beyond the joint as.

In order to reinforce and strengthen the structure at the joint a: where it is most lia ble to break when the switch is in service, I have provided the tip D with an integral reinforcing device that is arranged at the joint on, said reinforcing device preferably being in the form of-a laterally-projecbingbracket or clip E that serves to connect one of the switch rods C to the switch rail A.

The clip E is provided with a horizontallydisposed base portion '5 that projects laserally from the lower edge of the web 4: of

-the tip D, so that it will bear upon one lid able fastening device 7 that passes vertically through said parts. The case portion.

of the clip E is reinforced and strengthened by one or more vertically-disposed ribs or flanges that are integrally connected to same and to the vertical web at of the tip D, the clip E herein shown having two reinforcing ribs 5. whose upper edges taper downwardly and merge into the yoke-shaped have formed the tip D in such a manner that fee integral portions on same bear against both sides of the webv of the switch rail over which the wheel tread portion 1 of the tip extends. It is immaterial how the tip D is formed to accomplish this result, as my broad idea consists. in providing the tip with one or more integral portions that cooperate with the portion of the switch rail on which the tip is mounted, to prevent the tip from moving laterally away from the switch rail. In the embodiment of my invention herein illustrated the upper portion of the tip D is provided with a longitudinally-disposed groove 8 that receives the upper edge portion of the web 2 ,of the switch rail, thus forming a flange 9 on the tip that extends parallel to the web 4: of-

the tip. Said flange 9 may be of any preferred depth and length, or, if desired, the tip D may be provided with one or more short lugs or hook-shaped portions that merely lap over the upper edge of the web 2 of the switch rail. The upper edge of that portion of the web 2 of the switch rail that fits in the groove 8 in the tip is preferably tapered or made substantially wedgeshaped in cross section and the groove 8 is correspondingly shaped, as shown in Fig. 5, so as to overcome the necessityof machining the tip during the operation of combining it with the switch rail. If desired, a splice bar 10 can be arranged on the inner side of the web of the switch rail in parallel relation to the web 4 of the tip, as shown in Figs. 3, 4 and 5, so as to strengthen the connection between the tip D and the switch rail.

A manganese tip split switch of the construction above described is exceptionally strong and rigid, owing to the'fact that the two functions,-namely, it reinforces and strengthens the complete structure, and it a constitutes an integral switch rod clip that is not apt to work loose. The web of the switch rail extends throughout the entire -length of the tip, and as the tip is provided split switch of the construction above described can be manufactured cheaply,

, owing to the elimination of separate switch rod clips and to the novel manner inwhich the tip is combined with the switch rail. Furthermore, as the switch rodv clip is made of manganese steel or some other suitable metal that is harder than the metal heretofore used for switch rod clips, the hole in the clip through which the switch rod bolt passes will not wear or become enlarged, thus overcoming the necessity of frequently replacing the switch rod clip, and consequently, reducing the cost of maintenance.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is:
